I think it is not difficult from a technical standpoint.
The attached patch adds DETAIL messages to duplicate key value error:
postgres=# INSERT INTO tbl(pk1, pk2) VALUES ('A', 1);
ERROR: duplicate key value violates unique constraint "tbl_pkey"
DETAIL: Key (pk1,pk2)=(A,1) already exists.
If no objection, I'd like to submit the patch to the next commit-fest (8.5).
